| Description | Without cryptographic integrity protections, system
executables and files can be altered by unauthorized users without
detection.
The RPM package management system can check the hashes of
installed software packages, including many that are important to system
security.
To verify that the cryptographic hash of system files and commands matches vendor
values, run the following command to list which files on the system
have hashes that differ from what is expected by the RPM database:
$ rpm -Va --noconfig | grep '^..5'
A "c" in the second column indicates that a file is a configuration file, which
may appropriately be expected to change. If the file was not expected to
change, investigate the cause of the change using audit logs or other means.
The package can then be reinstalled to restore the file.
Run the following command to determine which package owns the file:
$ rpm -qf FILENAME
The package can be reinstalled from a dnf repository using the command:
$ sudo dnf reinstall PACKAGENAME
Alternatively, the package can be reinstalled from trusted media using the command:
$ sudo rpm -Uvh PACKAGENAME |
| Rationale | The hashes of important files like system executables should match the
information given by the RPM database. Executables with erroneous hashes could
be a sign of nefarious activity on the system. |

| Description | To enable FIPS mode, run the following command:
fips-mode-setup --enable
The fips-mode-setup command will configure the system in
FIPS mode by automatically configuring the following:
- Setting the kernel FIPS mode flag (
/proc/sys/crypto/fips_enabled) to 1 - Creating
/etc/system-fips - Setting the system crypto policy in
/etc/crypto-policies/config to FIPS - Loading the Dracut
fips module

protect data. The operating system must implement cryptographic modules adhering to the higher
standards approved by the federal government since this provides assurance they have been tested
and validated. |

| Description | To configure the system cryptography policy to use ciphers only from the FIPS
policy, run the following command:
$ sudo update-crypto-policies --set FIPS
The rule checks if settings for selected crypto policy are configured as expected. Configuration files in the /etc/crypto-policies/back-ends are either symlinks to correct files provided by Crypto-policies package or they are regular files in case crypto policy customizations are applied.
Crypto policies may be customized by crypto policy modules, in which case it is delimited from the base policy using a colon. |
| Rationale | Centralized cryptographic policies simplify applying secure ciphers across an operating system and
the applications that run on that operating system. Use of weak or untested encryption algorithms
undermines the purposes of utilizing encryption to protect data. |
| Warnings | warning
The system needs to be rebooted for these changes to take effect. warning
System Crypto Modules must be provided by a vendor that undergoes
FIPS-140 certifications.
FIPS-140 is applicable to all Federal agencies that use
cryptographic-based security systems to protect sensitive information
in computer and telecommunication systems (including voice systems) as
defined in Section 5131 of the Information Technology Management Reform
Act of 1996, Public Law 104-106. This standard shall be used in
designing and implementing cryptographic modules that Federal
departments and agencies operate or are operated for them under
contract. See https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.140-2.pdf
To meet this, the system has to have cryptographic software provided by
a vendor that has undergone this certification. This means providing
documentation, test results, design information, and independent third
party review by an accredited lab. While open source software is
capable of meeting this, it does not meet FIPS-140 unless the vendor
submits to this process. |

allowed-failures to 3 or less.
To enable, add or edit allowed-failures to
/etc/dconf/db/distro.d/00-security-settings. For example:
[org/gnome/login-screen]
allowed-failures=3
Once the setting has been added, add a lock to
/etc/dconf/db/distro.d/locks/00-security-settings-lock to prevent user modification.
For example:
/org/gnome/login-screen/allowed-failures
After the settings have been set, run dconf update. |
| Rationale | Setting the password retry prompts that are permitted on a per-session basis to a low value
requires some software, such as SSH, to re-connect. This can slow down and
draw additional attention to some types of password-guessing attacks. |

| Description | The GNOME Display Manager (GDM) can allow users to automatically login without
user interaction or credentials. User should always be required to authenticate themselves
to the system that they are authorized to use. To disable user ability to automatically
login to the system, set the AutomaticLoginEnable to false in the

| Description | To activate the screensaver in the GNOME3 desktop after a period of inactivity,
add or set idle-activation-enabled to true in
/etc/dconf/db/local.d/00-security-settings. For example:
[org/gnome/desktop/screensaver]
idle-activation-enabled=true
Once the setting has been added, add a lock to
/etc/dconf/db/local.d/locks/00-security-settings-lock to prevent user modification.
For example:
/org/gnome/desktop/screensaver/idle-activation-enabled
After the settings have been set, run dconf update. |
| Rationale | A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate
physical vicinity of the information system but does not logout because of the temporary nature of the absence.
Rather than relying on the user to manually lock their operating system session prior to vacating the vicinity,
GNOME desktops can be configured to identify when a user's session has idled and take action to initiate the
session lock.
Enabling idle activation of the screensaver ensures the screensaver will
be activated after the idle delay. Applications requiring continuous,
real-time screen display (such as network management products) require the
login session does not have administrator rights and the display station is located in a
controlled-access area. |

| Description | By default, DConf uses a binary database as a data backend.
The system-level database is compiled from keyfiles in the /etc/dconf/db/
directory by the dconf update command. More specifically, content present
in the following directories:
/etc/dconf/db/distro.d
/etc/dconf/db/local.d |
| Rationale | Unlike text-based keyfiles, the binary database is impossible to check by OVAL.
Therefore, in order to evaluate dconf configuration, both have to be true at the same time -
configuration files have to be compliant, and the database needs to be more recent than those keyfiles,
which gives confidence that it reflects them. |

| Description | To ensure the system can cryptographically verify base software
packages come from Fedora (and to connect to the Fedora Network to
receive them), the Fedora GPG key must properly be installed.
To install the Fedora GPG key, run one of the commands below, depending on your Fedora vesion:
$ sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-34-primary "
$ sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-33-primary " |
| Rationale | Changes to software components can have significant effects on the
overall security of the operating system. This requirement ensures
the software has not been tampered with and that it has been provided
by a trusted vendor. The Fedora GPG key is necessary to
cryptographically verify packages are from Fedora." |

| Description | The gpgcheck option controls whether
RPM packages' signatures are always checked prior to installation.
To configure dnf to check package signatures before installing
them, ensure the following line appears in /etc/dnf/dnf.conf in
the [main] section:
gpgcheck=1 |
| Rationale | Changes to any software components can have significant effects on the
overall security of the operating system. This requirement ensures the
software has not been tampered with and that it has been provided by a
trusted vendor.
Accordingly, patches, service packs, device drivers, or operating system
components must be signed with a certificate recognized and approved by the
organization.
Verifying the authenticity of the software prior to installation
validates the integrity of the patch or upgrade received from a vendor.
This ensures the software has not been tampered with and that it has been
provided by a trusted vendor. Self-signed certificates are disallowed by
this requirement. Certificates used to verify the software must be from an
approved Certificate Authority (CA). |

| Description | In the default graphical environment, displaying a login warning banner
in the GNOME Display Manager's login screen can be enabled on the login
screen by setting banner-message-enable to true.
To enable, add or edit banner-message-enable to
/etc/dconf/db/distro.d/00-security-settings. For example:
[org/gnome/login-screen]
banner-message-enable=true
Once the setting has been added, add a lock to
/etc/dconf/db/distro.d/locks/00-security-settings-lock to prevent user modification.
For example:
/org/gnome/login-screen/banner-message-enable
After the settings have been set, run dconf update.
The banner text must also be set. |
| Rationale | Display of a standardized and approved use notification before granting access to the operating system

Executive Orders, directives, policies, regulations, standards, and guidance.
For U.S. Government systems, system use notifications are required only for access via login interfaces
with human users and are not required when such human interfaces do not exist. |

| Description | In the default graphical environment, configuring the login warning banner text
in the GNOME Display Manager's login screen can be configured on the login
screen by setting banner-message-text to 'APPROVED_BANNER'
where APPROVED_BANNER is the approved banner for your environment.
To enable, add or edit banner-message-text to
/etc/dconf/db/distro.d/00-security-settings. For example:
[org/gnome/login-screen]
banner-message-text='APPROVED_BANNER'
Once the setting has been added, add a lock to
/etc/dconf/db/distro.d/locks/00-security-settings-lock to prevent user modification.
For example:
/org/gnome/login-screen/banner-message-text
After the settings have been set, run dconf update.
When entering a warning banner that spans several lines, remember
to begin and end the string with ' and use \n for new lines. |
| Rationale | An appropriate warning message reinforces policy awareness during the logon
process and facilitates possible legal action against attackers. |

To configure the system login banner edit /etc/issue. Replace the
default text with a message compliant with the local site policy or a legal
disclaimer.
The DoD required text is either:
You are accessing a U.S. Government (USG) Information System (IS) that
is provided for USG-authorized use only. By using this IS (which includes
any device attached to this IS), you consent to the following conditions:
-The USG routinely intercepts and monitors communications on this IS
for purposes including, but not limited to, penetration testing, COMSEC
monitoring, network operations and defense, personnel misconduct (PM), law
enforcement (LE), and counterintelligence (CI) investigations.
-At any time, the USG may inspect and seize data stored on this IS.
-Communications using, or data stored on, this IS are not private,
are subject to routine monitoring, interception, and search, and may be
disclosed or used for any USG-authorized purpose.
-This IS includes security measures (e.g., authentication and access
controls) to protect USG interests -- not for your personal benefit or
privacy.
-Notwithstanding the above, using this IS does not constitute consent
to PM, LE or CI investigative searching or monitoring of the content of
privileged communications, or work product, related to personal
representation or services by attorneys, psychotherapists, or clergy, and
their assistants. Such communications and work product are private and
confidential. See User Agreement for details.
OR:

| Description | This rule configures the system to lock out accounts after a number of incorrect login attempts
using pam_faillock.so.
pam_faillock.so module requires multiple entries in pam files. These entries must be carefully
defined to work as expected. In order to avoid any errors when manually editing these files,
it is recommended to use the appropriate tools, such as authselect or authconfig,
depending on the OS version. |
| Rationale | Locking out user accounts after a number of incorrect attempts prevents direct password
guessing attacks. In combination with the silent option, user enumeration attacks
are also mitigated. |
| Warnings | warning
If the system relies on authselect tool to manage PAM settings, the remediation
will also use authselect tool. However, if any manual modification was made in
PAM files, the authselect integrity check will fail and the remediation will be
aborted in order to preserve intentional changes. In this case, an informative message will
be shown in the remediation report.
If the system supports the /etc/security/faillock.conf file, the pam_faillock
parameters should be defined in faillock.conf file. |

| Description | Utilizing pam_faillock.so, the fail_interval directive configures the system
to lock out an account after a number of incorrect login attempts within a specified time
period. First make sure the feature is enabled using the following command:
Then edit the /etc/security/faillock.conf file as follows:
- add, uncomment or edit the following line:
fail_interval = 900 - add or uncomment the following line:
silent
|
| Rationale | By limiting the number of failed logon attempts the risk of unauthorized system
access via user password guessing, otherwise known as brute-forcing, is reduced.
Limits are imposed by locking the account. |
| Warnings | warning
If the system relies on authselect tool to manage PAM settings, the remediation
will also use authselect tool. However, if any manual modification was made in
PAM files, the authselect integrity check will fail and the remediation will be
aborted in order to preserve intentional changes. In this case, an informative message will
be shown in the remediation report.
If the system supports the /etc/security/faillock.conf file, the pam_faillock
parameters should be defined in faillock.conf file. |

| Description | This rule configures the system to lock out accounts during a specified time period after a
number of incorrect login attempts using pam_faillock.so.
pam_faillock.so module requires multiple entries in pam files. These entries must be carefully
defined to work as expected. In order to avoid any errors when manually editing these files,
it is recommended to use the appropriate tools, such as authselect or authconfig,
depending on the OS version. |
| Rationale | Locking out user accounts after a number of incorrect attempts prevents direct password
guessing attacks. Ensuring that an administrator is involved in unlocking locked accounts
draws appropriate attention to such situations. |
| Warnings | warning
If the system relies on authselect tool to manage PAM settings, the remediation
will also use authselect tool. However, if any manual modification was made in
PAM files, the authselect integrity check will fail and the remediation will be
aborted in order to preserve intentional changes. In this case, an informative message will
be shown in the remediation report.
If the system supports the /etc/security/faillock.conf file, the pam_faillock
parameters should be defined in faillock.conf file. |

| Description | The pam_pwquality module's dcredit parameter controls requirements for
usage of digits in a password. When set to a negative number, any password will be required to
contain that many digits. When set to a positive number, pam_pwquality will grant +1 additional
length credit for each digit. Modify the dcredit setting in
/etc/security/pwquality.conf to require the use of a digit in passwords. |
| Rationale | Use of a complex password helps to increase the time and resources required
to compromise the password. Password complexity, or strength, is a measure of
the effectiveness of a password in resisting attempts at guessing and brute-force
attacks.
Password complexity is one factor of several that determines how long it takes
to crack a password. The more complex the password, the greater the number of
possible combinations that need to be tested before the password is compromised.
Requiring digits makes password guessing attacks more difficult by ensuring a larger
search space. |

| Description | The pam_pwquality module's minlen parameter controls requirements for
minimum characters required in a password. Add minlen=12
after pam_pwquality to set minimum password length requirements. |
| Rationale | The shorter the password, the lower the number of possible combinations
that need to be tested before the password is compromised.
Password complexity, or strength, is a measure of the effectiveness of a
password in resisting attempts at guessing and brute-force attacks.
Password length is one factor of several that helps to determine strength
and how long it takes to crack a password. Use of more characters in a password
helps to exponentially increase the time and/or resources required to
compromose the password. |

| Description | The pam_pwquality module's ocredit= parameter controls requirements for
usage of special (or "other") characters in a password. When set to a negative number,
any password will be required to contain that many special characters.
When set to a positive number, pam_pwquality will grant +1
additional length credit for each special character. Modify the ocredit setting
in /etc/security/pwquality.conf to equal -1
to require use of a special character in passwords. |

| Description | To configure the number of retry prompts that are permitted per-session:
Edit the pam_pwquality.so statement in
/etc/pam.d/system-auth to show
retry=3, or a lower value if site
policy is more restrictive. The DoD requirement is a maximum of 3 prompts
per session. |
| Rationale | Setting the password retry prompts that are permitted on a per-session basis to a low value
requires some software, such as SSH, to re-connect. This can slow down and
draw additional attention to some types of password-guessing attacks. Note that this
is different from account lockout, which is provided by the pam_faillock module. |

| Description | To enable console screen locking, install the screen package.
The screen package can be installed with the following command:
$ sudo dnf install screen
Instruct users to begin new terminal sessions with the following command:
$ screen
The console can now be locked with the following key combination:
ctrl+a x |
| Rationale | A session time-out lock is a temporary action taken when a user stops work and moves away from the immediate
physical vicinity of the information system but does not logout because of the temporary nature of the absence.
Rather than relying on the user to manually lock their operation system session prior to vacating the vicinity,
operating systems need to be able to identify when a user's session has idled and take action to initiate the
session lock.
The screen package allows for a session lock to be implemented and configured. |

| Description | SystemD's debug-shell service is intended to
diagnose SystemD related boot issues with various systemctl
commands. Once enabled and following a system reboot, the root shell
will be available on tty9 which is access by pressing
CTRL-ALT-F9. The debug-shell service should only be used
for SystemD related issues and should otherwise be disabled.
By default, the debug-shell SystemD service is already disabled.
The debug-shell service can be disabled with the following command:
$ sudo systemctl mask --now debug-shell.service |
| Rationale | This prevents attackers with physical access from trivially bypassing security
on the machine through valid troubleshooting configurations and gaining root
access when the system is rebooted. |

| Description | Fedora systems support an "interactive boot" option that can
be used to prevent services from being started. On a Fedora
system, interactive boot can be enabled by providing a 1,
yes, true, or on value to the
systemd.confirm_spawn kernel argument in /etc/default/grub.
Remove any instance of systemd.confirm_spawn=(1|yes|true|on) from
the kernel arguments in that file to disable interactive boot. It is also
required to change the runtime configuration, run:
/sbin/grubby --update-kernel=ALL --remove-args="systemd.confirm_spawn" |
| Rationale | Using interactive boot, the console user could disable auditing, firewalls,
or other services, weakening system security. |

| Description | Single-user mode is intended as a system recovery
method, providing a single user root access to the system by
providing a boot option at startup. By default, no authentication
is performed if single-user mode is selected.
By default, single-user mode is protected by requiring a password and is set
in /usr/lib/systemd/system/rescue.service. |
| Rationale | This prevents attackers with physical access from trivially bypassing security
on the machine and gaining root access. Such accesses are further prevented
by configuring the bootloader password. |

| Description | To specify password length requirements for new accounts, edit the file
/etc/login.defs and add or correct the following line:
PASS_MIN_LEN 15
The DoD requirement is 15.
The FISMA requirement is 12.
The profile requirement is
15.
If a program consults /etc/login.defs and also another PAM module
(such as pam_pwquality) during a password change operation, then
the most restrictive must be satisfied. See PAM section for more
information about enforcing password quality requirements. |
| Rationale | Requiring a minimum password length makes password
cracking attacks more difficult by ensuring a larger
search space. However, any security benefit from an onerous requirement
must be carefully weighed against usability problems, support costs, or counterproductive
behavior that may result. |

| Description | If an account is configured for password authentication
but does not have an assigned password, it may be possible to log
into the account without authentication. Remove any instances of the
nullok in
/etc/pam.d/system-auth
to prevent logins with empty passwords. |
| Rationale | If an account has an empty password, anyone could log in and
run commands with the privileges of that account. Accounts with
empty passwords should never be used in operational environments. |
| Warnings | warning
If the system relies on authselect tool to manage PAM settings, the remediation
will also use authselect tool. However, if any manual modification was made in
PAM files, the authselect integrity check will fail and the remediation will be
aborted in order to preserve intentional changes. In this case, an informative message will
be shown in the remediation report.
Note that this rule is not applicable for systems running within a
container. Having user with empty password within a container is not
considered a risk, because it should not be possible to directly login into
a container anyway. |

| Description | Setting the TMOUT option in /etc/profile ensures that
all user sessions will terminate based on inactivity. The TMOUT
setting in a file loaded by /etc/profile, e.g.
/etc/profile.d/tmout.sh should read as follows:
TMOUT=600 |
| Rationale | Terminating an idle session within a short time period reduces
the window of opportunity for unauthorized personnel to take control of a
management session enabled on the console or console port that has been
left unattended. |

use the augenrules program to read audit rules during daemon startup
(the default), add the following line to a file with suffix .rules in

If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S chmod -F auid>=1000 -F auid!=unset -F key=perm_mod

| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured to
use the augenrules program to read audit rules during daemon startup
(the default), add the following line to a file with suffix .rules in
the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S fchmod -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fchmod -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S fchmod -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fchmod -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following line to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S fchown -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fchown -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S fchown -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fchown -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following line to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S fchownat -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fchownat -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S fchownat -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fchownat -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following line to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S fsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following line to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S lremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S lremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S lremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S lremovexattr -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following line to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S lsetxattr -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect file permission
changes for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following line to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S setxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S setxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S setxattr -F auid>=1000 -F auid!=unset -F key=perm_mod
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S setxattr -F auid>=1000 -F auid!=unset -F key=perm_mod |
| Rationale | The changing of file permissions could indicate that a user is attempting to
gain access to information that would otherwise be disallowed. Auditing DAC modifications
can facilitate the identification of patterns of abuse among both authorized and
unauthorized users. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect any execution attempt
of the chcon command for all users and root. If the auditd
daemon is configured to use the augenrules program to read audit rules
during daemon startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F path=/usr/bin/chcon -F auid>=1000 -F auid!=unset -F key=privileged
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F path=/usr/bin/chcon -F auid>=1000 -F auid!=unset -F key=privileged |
| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.
Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity. |

| Description | At a minimum, the audit system should collect any execution attempt
of the restorecon command for all users and root. If the auditd
daemon is configured to use the augenrules program to read audit rules
during daemon startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F path=/usr/sbin/restorecon -F auid>=1000 -F auid!=unset -F key=privileged
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F path=/usr/sbin/restorecon -F auid>=1000 -F auid!=unset -F key=privileged |
| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.
Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity. |

utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file, setting ARCH to either b32 or b64 as
appropriate for your system:
-a always,exit -F arch=ARCH -S rename -F auid>=1000 -F auid!=unset -F key=delete |

| Description | At a minimum, the audit system should collect file deletion events
for all users and root. If the auditd daemon is configured to use the
augenrules program to read audit rules during daemon startup (the
default), add the following line to a file with suffix .rules in the
directory /etc/audit/rules.d, setting ARCH to either b32 or b64 as
appropriate for your system:
-a always,exit -F arch=ARCH -S renameat -F auid>=1000 -F auid!=unset -F key=delete
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file, setting ARCH to either b32 or b64 as
appropriate for your system:
-a always,exit -F arch=ARCH -S renameat -F auid>=1000 -F auid!=unset -F key=delete |
| Rationale | Auditing file deletions will create an audit trail for files that are removed
from the system. The audit trail could aid in system troubleshooting, as well as, detecting
malicious processes that attempt to delete log files to conceal their presence. |

| Description | At a minimum, the audit system should collect file deletion events
for all users and root. If the auditd daemon is configured to use the
augenrules program to read audit rules during daemon startup (the
default), add the following line to a file with suffix .rules in the
directory /etc/audit/rules.d, setting ARCH to either b32 or b64 as
appropriate for your system:
-a always,exit -F arch=ARCH -S unlinkat -F auid>=1000 -F auid!=unset -F key=delete
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file, setting ARCH to either b32 or b64 as
appropriate for your system:
-a always,exit -F arch=ARCH -S unlinkat -F auid>=1000 -F auid!=unset -F key=delete |
| Rationale | Auditing file deletions will create an audit trail for files that are removed
from the system. The audit trail could aid in system troubleshooting, as well as, detecting
malicious processes that attempt to delete log files to conceal their presence. |

| Description | The audit system should collect unsuccessful file permission change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S chmod -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S chmod -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S chmod -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S chmod -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | The audit system should collect unsuccessful file ownership change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S chown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S chown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S chown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S chown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change ownership of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S creat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S creat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access |
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | The audit system should collect unsuccessful file ownership change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S fchown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S fchown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S fchown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S fchown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change ownership of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | The audit system should collect unsuccessful file ownership change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S fchownat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S fchownat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change ownership of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S ftruncate -F exiu=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access |
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | The audit system should collect unsuccessful file ownership change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S lchown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S lchown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S lchown -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S lchown -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change ownership of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S lchown,fchown,chown,fchownat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | The audit system should collect unsuccessful file permission change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S lremovexattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S lremovexattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S lremovexattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S lremovexattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | The audit system should collect unsuccessful file permission change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S lsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S lsetxattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S lsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S lsetxattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon

-a always,exit -F arch=b32 -S open -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S open -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S open -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access |

Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S open_by_handle_at -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open_by_handle_at -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open_by_handle_at,truncate,ftruncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S open_by_handle_at,truncate,ftruncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access |
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | The audit system should collect unauthorized file accesses for
all users and root. The open_by_handle_at syscall can be used to create new files
when O_CREAT flag is specified.
The following auidt rules will asure that unsuccessful attempts to create a
file via open_by_handle_at syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
|
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create |

| Description | The audit system should collect detailed unauthorized file accesses for
all users and root. The open_by_handle_at syscall can be used to modify files
if called for write operation of with O_TRUNC_WRITE flag.
The following auidt rules will asure that unsuccessful attempts to modify a
file via open_by_handle_at syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
|
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification |

| Description | The audit system should collect detailed unauthorized file
accesses for all users and root.
To correctly identify unsuccessful creation, unsuccessful modification and unsuccessful access
of files via open_by_handle_at syscall the audit rules collecting these events need to be in certain order.
The more specific rules need to come before the less specific rules. The reason for that is that more
specific rules cover a subset of events covered in the less specific rules, thus, they need to come
before to not be overshadowed by less specific rules, which match a bigger set of events.
Make sure that rules for unsuccessful calls of open_by_handle_at syscall are in the order shown below.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), check the order of
rules below in a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, check the order of rules below in
/etc/audit/audit.rules file.

If the system is 64 bit then also add the following lines:

-a always,exit -F arch=b64 -S open_by_handle_at -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
|
| Rationale | The more specific rules cover a subset of events covered by the less specific rules.
By ordering them from more specific to less specific, it is assured that the less specific
rule will not catch events better recorded by the more specific rule. |

| Description | The audit system should collect unauthorized file accesses for
all users and root. The open syscall can be used to create new files
when O_CREAT flag is specified.
The following auidt rules will asure that unsuccessful attempts to create a
file via open syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
|
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create |

| Description | The audit system should collect detailed unauthorized file accesses for
all users and root. The open syscall can be used to modify files
if called for write operation of with O_TRUNC_WRITE flag.
The following auidt rules will asure that unsuccessful attempts to modify a
file via open syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
|
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification |

| Description | The audit system should collect detailed unauthorized file
accesses for all users and root.
To correctly identify unsuccessful creation, unsuccessful modification and unsuccessful access
of files via open syscall the audit rules collecting these events need to be in certain order.
The more specific rules need to come before the less specific rules. The reason for that is that more
specific rules cover a subset of events covered in the less specific rules, thus, they need to come
before to not be overshadowed by less specific rules, which match a bigger set of events.
Make sure that rules for unsuccessful calls of open syscall are in the order shown below.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), check the order of
rules below in a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, check the order of rules below in
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S open -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
-a always,exit -F arch=b32 -S open -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open -F a1&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open -F a1&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S open -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
-a always,exit -F arch=b64 -S open -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
|
| Rationale | The more specific rules cover a subset of events covered by the less specific rules.
By ordering them from more specific to less specific, it is assured that the less specific
rule will not catch events better recorded by the more specific rule. |

| Description | At a minimum, the audit system should collect unauthorized file
accesses for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b32 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access |
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description | The audit system should collect unauthorized file accesses for
all users and root. The openat syscall can be used to create new files
when O_CREAT flag is specified.
The following auidt rules will asure that unsuccessful attempts to create a
file via openat syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S openat -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S openat -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S openat -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S openat -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
|
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create |

| Description | The audit system should collect detailed unauthorized file accesses for
all users and root. The openat syscall can be used to modify files
if called for write operation of with O_TRUNC_WRITE flag.
The following auidt rules will asure that unsuccessful attempts to modify a
file via openat syscall are collected.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rules below to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rules below to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S openat -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S openat -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S openat -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S openat -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
|
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification |

| Description | The audit system should collect detailed unauthorized file
accesses for all users and root.
To correctly identify unsuccessful creation, unsuccessful modification and unsuccessful access
of files via openat syscall the audit rules collecting these events need to be in certain order.
The more specific rules need to come before the less specific rules. The reason for that is that more
specific rules cover a subset of events covered in the less specific rules, thus, they need to come
before to not be overshadowed by less specific rules, which match a bigger set of events.
Make sure that rules for unsuccessful calls of openat syscall are in the order shown below.
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), check the order of
rules below in a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, check the order of rules below in
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S openat -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S openat -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b32 -S openat -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S openat -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b32 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
-a always,exit -F arch=b32 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S openat -F a2&0100 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S openat -F a2&0100 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-create
-a always,exit -F arch=b64 -S openat -F a2&01003 -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S openat -F a2&01003 -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-modification
-a always,exit -F arch=b64 -S openat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
-a always,exit -F arch=b64 -S openat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-access
|
| Rationale | The more specific rules cover a subset of events covered by the less specific rules.
By ordering them from more specific to less specific, it is assured that the less specific
rule will not catch events better recorded by the more specific rule. |

| Description | The audit system should collect unsuccessful file permission change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S removexattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S removexattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S removexattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S removexattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

| Description | The audit system should collect unsuccessful file deletion
attempts for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S rename -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b32 -S rename -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S rename -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b64 -S rename -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete |
| Rationale | Unsuccessful attempts to delete files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S unlink,unlinkat,rename,renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-delete |

| Description |
The audit system should collect unsuccessful file deletion
attempts for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b32 -S renameat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b64 -S renameat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete |
| Rationale | Unsuccessful attempts to delete files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S unlink,unlinkat,rename,renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-delete

| Description | The audit system should collect unsuccessful file permission change
attempts for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S setxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b32 -S setxattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S setxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change
-a always,exit -F arch=b64 -S setxattr -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |
| Rationale | Unsuccessful attempts to change permissions of files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the audit rule checks a
system call independently of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S chmod,fchmod,fchmodat,setxattr,lsetxattr,fsetxattr -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-perm-change |

-a always,exit -F arch=b64 -S truncate -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=access
-a always,exit -F arch=b64 -S truncate -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=access |
| Rationale | Unsuccessful attempts to access files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping these system
calls with others as identifying earlier in this guide is more efficient. |

| Description |
The audit system should collect unsuccessful file deletion
attempts for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S unlink -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b32 -S unlink -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S unlink -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b64 -S unlink -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete |
| Rationale | Unsuccessful attempts to delete files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S unlink,unlinkat,rename,renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-delete

| Description |
The audit system should collect unsuccessful file deletion
attempts for all users and root. If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file.
-a always,exit -F arch=b32 -S unlinkat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b32 -S unlinkat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
If the system is 64 bit then also add the following lines:
-a always,exit -F arch=b64 -S unlinkat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete
-a always,exit -F arch=b64 -S unlinkat -F exit=-EPERM -F auid>=1000 -F auid!=unset -F key=unsuccessful-delete |
| Rationale | Unsuccessful attempts to delete files could be an indicator of malicious activity on a system. Auditing
these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S unlink,unlinkat,rename,renameat -F exit=-EACCES -F auid>=1000 -F auid!=unset -F key=unsuccesful-delete

| Description | To capture kernel module unloading events, use following line, setting ARCH to
either b32 for 32-bit system, or having two lines for both b32 and b64 in case your system is 64-bit:
-a always,exit -F arch=ARCH -S delete_module -F key=modules
Place to add the line depends on a way auditd daemon is configured. If it is configured
to use the augenrules program (the default), add the line to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl utility,
add the line to file /etc/audit/audit.rules. |
| Rationale | The removal of kernel modules can be used to alter the behavior of
the kernel and potentially introduce malicious code into kernel space. It is important
to have an audit trail of modules that have been introduced into the kernel. |

| Description | To capture kernel module loading events, use following line, setting ARCH to
either b32 for 32-bit system, or having two lines for both b32 and b64 in case your system is 64-bit:
-a always,exit -F arch=ARCH -S init_module -F key=modules
Place to add the line depends on a way auditd daemon is configured. If it is configured
to use the augenrules program (the default), add the line to a file with suffix
.rules in the directory /etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl utility,
add the line to file /etc/audit/audit.rules. |
| Rationale | The addition of kernel modules can be used to alter the behavior of
the kernel and potentially introduce malicious code into kernel space. It is important
to have an audit trail of modules that have been introduced into the kernel. |

| Description | The audit system already collects login information for all users
and root. If the auditd daemon is configured to use the
augenrules program to read audit rules during daemon startup (the
default), add the following lines to a file with suffix .rules in the
directory /etc/audit/rules.d in order to watch for attempted manual
edits of files involved in storing logon events:
-w /var/log/tallylog -p wa -k logins
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file in order to watch for unattempted manual
edits of files involved in storing logon events:
-w /var/log/tallylog -p wa -k logins |
| Rationale | Manual editing of these files may indicate nefarious activity, such
as an attacker attempting to remove evidence of an intrusion. |

| Description | At a minimum, the audit system should collect the execution of
privileged commands for all users and root. If the auditd daemon is

| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.
Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity. |

| Description | At a minimum, the audit system should collect the execution of
privileged commands for all users and root. If the auditd daemon is
configured to use the augenrules program to read audit rules during
daemon startup (the default), add a line of the following form to a file with
suffix .rules in the directory /etc/audit/rules.d:
-a always,exit -F path=/usr/bin/gpasswd -F auid>=1000 -F auid!=unset -F key=privileged
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add a line of the following
form to /etc/audit/audit.rules:
-a always,exit -F path=/usr/bin/gpasswd -F auid>=1000 -F auid!=unset -F key=privileged |
| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.

| Description | At a minimum, the audit system should collect the execution of
privileged commands for all users and root. If the auditd daemon is
configured to use the augenrules program to read audit rules during
daemon startup (the default), add a line of the following form to a file with
suffix .rules in the directory /etc/audit/rules.d:
-a always,exit -F path=/usr/bin/passwd -F auid>=1000 -F auid!=unset -F key=privileged
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add a line of the following
form to /etc/audit/audit.rules:
-a always,exit -F path=/usr/bin/passwd -F auid>=1000 -F auid!=unset -F key=privileged |
| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.
Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity. |

| Description | At a minimum, the audit system should collect the execution of
privileged commands for all users and root. If the auditd daemon is
configured to use the augenrules program to read audit rules during
daemon startup (the default), add a line of the following form to a file with
suffix .rules in the directory /etc/audit/rules.d:
-a always,exit -F path=/usr/bin/sudo -F auid>=1000 -F auid!=unset -F key=privileged
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add a line of the following
form to /etc/audit/audit.rules:
-a always,exit -F path=/usr/bin/sudo -F auid>=1000 -F auid!=unset -F key=privileged |
| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.
Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity. |

| Description | At a minimum, the audit system should collect the execution of
privileged commands for all users and root. If the auditd daemon is
configured to use the augenrules program to read audit rules during
daemon startup (the default), add a line of the following form to a file with
suffix .rules in the directory /etc/audit/rules.d:
-a always,exit -F path=/usr/sbin/userhelper -F auid>=1000 -F auid!=unset -F key=privileged
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add a line of the following
form to /etc/audit/audit.rules:
-a always,exit -F path=/usr/sbin/userhelper -F auid>=1000 -F auid!=unset -F key=privileged |
| Rationale | Misuse of privileged functions, either intentionally or unintentionally by
authorized users, or by unauthorized external entities that have compromised system accounts,
is a serious and ongoing concern and can have significant adverse impacts on organizations.
Auditing the use of privileged functions is one way to detect such misuse and identify
the risk from insider and advanced persistent threats.
Privileged programs are subject to escalation-of-privilege attacks,
which attempt to subvert their normal role of providing some necessary but
limited capability. As such, motivation exists to monitor these programs for
unusual activity. |

| Description | The audit system should collect write events to /etc/group file for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S open -F a1&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S open -F a1&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S open -F a1&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify |
| Rationale | Creation of groups through direct edition of /etc/group could be an indicator of malicious activity on a system.

Note that these rules can be configured in a

| Description | The audit system should collect write events to /etc/group file for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S openat -F a2&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S openat -F a2&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S openat -F a2&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify |
| Rationale | Creation of groups through direct edition of /etc/group could be an indicator of malicious activity on a system.
Auditing these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&03 -F path=/etc/group -F auid>=1000 -F auid!=unset -F key=modify |

| Description | The audit system should collect write events to /etc/gshadow file for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&03 -F path=/etc/gshadow -F auid>=1000 -F auid!=unset -F key=user-modify
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&03 -F path=/etc/gshadow -F auid>=1000 -F auid!=unset -F key=user-modify
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&03 -F path=/etc/gshadow -F auid>=1000 -F auid!=unset -F key=user-modify |
| Rationale | Creation of users through direct edition of /etc/gshadow could be an indicator of malicious activity on a system.
Auditing these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&03 -F path=/etc/gshadow -F auid>=1000 -F auid!=unset -F key=user-modify |

| Description | The audit system should collect write events to /etc/passwd file for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S open -F a1&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S open -F a1&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S open -F a1&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify |
| Rationale | Creation of users through direct edition of /etc/passwd could be an indicator of malicious activity on a system.
Auditing these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S open -F a1&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify |

| Description | The audit system should collect write events to /etc/passwd file for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S openat -F a2&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S openat -F a2&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S openat -F a2&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify |
| Rationale | Creation of users through direct edition of /etc/passwd could be an indicator of malicious activity on a system.
Auditing these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S openat,open_by_handle_at -F a2&03 -F path=/etc/passwd -F auid>=1000 -F auid!=unset -F key=modify |

| Description | The audit system should collect write events to /etc/shadow file for all users and root.
If the auditd daemon is configured
to use the augenrules program to read audit rules during daemon
startup (the default), add the following lines to a file with suffix
.rules in the directory /etc/audit/rules.d:
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&03 -F path=/etc/shadow -F auid>=1000 -F auid!=unset -F key=user-modify
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following lines to
/etc/audit/audit.rules file:
-a always,exit -F arch=b32 -S open_by_handle_at -F a2&03 -F path=/etc/shadow -F auid>=1000 -F auid!=unset -F key=user-modify
If the system is 64 bit then also add the following line:
-a always,exit -F arch=b64 -S open_by_handle_at -F a2&03 -F path=/etc/shadow -F auid>=1000 -F auid!=unset -F key=user-modify |
| Rationale | Creation of users through direct edition of /etc/shadow could be an indicator of malicious activity on a system.
Auditing these events could serve as evidence of potential system compromise. |
| Warnings | warning
Note that these rules can be configured in a
number of ways while still achieving the desired effect. Here the system calls
have been placed independent of other system calls. Grouping system calls related
to the same event is more efficient. See the following example:
-a always,exit -F arch=b32 -S open,openat,open_by_handle_at -F a2&03 -F path=/etc/shadow -F auid>=1000 -F auid!=unset -F key=user-modify |

| Description | If the auditd daemon is configured to use the
augenrules program to read audit rules during daemon startup (the
default), add the following line to a file with suffix .rules in the
directory /etc/audit/rules.d in order to make the auditd configuration
immutable:
-e 2
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file in order to make the auditd configuration
immutable:
-e 2
With this setting, a reboot will be required to change any audit rules. |
| Rationale | Making the audit configuration immutable prevents accidental as
well as malicious modification of the audit rules, although it may be
problematic if legitimate changes are needed during system
operation |

If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the following line to
/etc/audit/audit.rules file:
-w /etc/sudoers -p wa -k actions
-w /etc/sudoers.d/ -p wa -k actions |
| Rationale | The actions taken by system administrators should be audited to keep a record
of what was executed on the system, as well as, for accountability purposes. |

| Description | The audit system should collect access events to read audit log directory.
The following audit rule will assure that access to audit log directory are
collected.
-a always,exit -F dir=/var/log/audit/ -F perm=r -F auid>=1000 -F auid!=unset -F key=access-audit-trail
If the auditd daemon is configured to use the augenrules
program to read audit rules during daemon startup (the default), add the
rule to a file with suffix .rules in the directory
/etc/audit/rules.d.
If the auditd daemon is configured to use the auditctl
utility to read audit rules during daemon startup, add the rule to
/etc/audit/audit.rules file. |
| Rationale | Attempts to read the logs should be recorded, suspicious access to audit log files could be an indicator of malicious activity on a system.
Auditing these events could serve as evidence of potential system compromise.' |

| Description | To ensure all processes can be audited, even those which start

Configure the default Grub2 kernel command line to contain audit=1 as follows:
# grub2-editenv - set "$(grub2-editenv - list | grep kernelopts) audit=1" |
| Rationale | Each process on the system carries an "auditable" flag which indicates whether
its activities can be audited. Although auditd takes care of enabling
this for all processes which launch after it does, adding the kernel argument
ensures it is set for every process during boot. |

| Rationale | audit_backlog_limit sets the queue length for audit events awaiting transfer
to the audit daemon. Until the audit daemon is up and running, all log messages
are stored in this queue. If the queue is overrun during boot process, the action
defined by audit failure flag is taken. |

| Description | The grub2 boot loader should have a superuser account and password
protection enabled to protect boot-time settings.
Since plaintext passwords are a security risk, generate a hash for the password
by running the following command:
# grub2-setpassword
When prompted, enter the password that was selected.
|
| Rationale | Password protection on the boot loader configuration ensures
users with physical access cannot trivially alter
important bootloader settings. These include which kernel to use,
and whether to enter single-user mode. |
| Warnings | warning
To prevent hard-coded passwords, automatic remediation of this control is not available. Remediation
must be automated as a component of machine provisioning, or followed manually as outlined above.
Also, do NOT manually add the superuser account and password to the
grub.cfg file as the grub2-mkconfig command overwrites this file. |

| Description | To configure rsyslog to send logs to a remote log server,
open /etc/rsyslog.conf and read and understand the last section of the file,
which describes the multiple directives necessary to activate remote
logging.
Along with these other directives, the system can be configured
to forward its logs to a particular log server by
adding or correcting one of the following lines,
substituting logcollector appropriately.
The choice of protocol depends on the environment of the system;
although TCP and RELP provide more reliable message delivery,
they may not be supported in all environments.
To use UDP for log message delivery:
*.* @logcollector
To use TCP for log message delivery:
*.* @@logcollector
To use RELP for log message delivery:
*.* :omrelp:logcollector
There must be a resolvable DNS CNAME or Alias record set to " logcollector" for logs to be sent correctly to the centralized logging utility. |
| Rationale | A log server (loghost) receives syslog messages from one or more
systems. This data can be used as an additional log source in the event a
system is compromised and its local logs are suspect. Forwarding log messages
to a remote loghost also provides system administrators with a centralized
place to view the status of multiple hosts within the enterprise. |

| Description | To set the default zone to drop for
the built-in default zone which processes incoming IPv4 and IPv6 packets,
modify the following line in
/etc/firewalld/firewalld.conf to be:
DefaultZone=drop |
| Rationale | In firewalld the default zone is applied only after all
the applicable rules in the table are examined for a match. Setting the
default zone to drop implements proper design for a firewall, i.e.
any packets which are not explicitly permitted should not be
accepted. |
| Warnings | warning
To prevent denying any access to the system, automatic remediation
of this control is not available. Remediation must be automated as
a component of machine provisioning, or followed manually as outlined
above. |

| Description | The nodev mount option can be used to prevent creation of device
files in /dev/shm. Legitimate character and block devices should
not exist within temporary directories like /dev/shm.
Add the nodev option to the fourth column of
/etc/fstab for the line which controls mounting of
/dev/shm. |
| Rationale | The only legitimate location for device files is the /dev directory
located on the root partition. The only exception to this is chroot jails. |

| Description | The noexec mount option can be used to prevent binaries
from being executed out of /dev/shm.
It can be dangerous to allow the execution of binaries
from world-writable temporary storage directories such as /dev/shm.
Add the noexec option to the fourth column of
/etc/fstab for the line which controls mounting of
/dev/shm. |
| Rationale | Allowing users to execute binaries from world-writable directories
such as /dev/shm can expose the system to potential compromise. |

| Description | To set the runtime status of the kernel.kptr_restrict kernel parameter, run the following command: $ sudo sysctl -w kernel.kptr_restrict=1
To make sure that the setting is persistent, add the following line to a file in the directory /etc/sysctl.d: kernel.kptr_restrict = 1 |
| Rationale | Exposing kernel pointers (through procfs or seq_printf()) exposes
kernel writeable structures that can contain functions pointers. If a write vulnereability occurs
in the kernel allowing a write access to any of this structure, the kernel can be compromise. This
option disallow any program withtout the CAP_SYSLOG capability from getting the kernel pointers addresses,
replacing them with 0. |

| Description | To enable poisoning of free pages,
add the argument page_poison=1 to the default
GRUB 2 command line for the Linux operating system.
Configure the default Grub2 kernel command line to contain page_poison=1 as follows:
# grub2-editenv - set "$(grub2-editenv - list | grep kernelopts) page_poison=1" |
| Rationale | Poisoning writes an arbitrary value to freed pages, so any modification or
reference to that page after being freed or before being initialized will be
detected and prevented.
This prevents many types of use-after-free vulnerabilities at little performance cost.
Also prevents leak of data and detection of corrupted memory. |

Configure the default Grub2 kernel command line to contain slub_debug=P as follows:

| Description | Device files, which are used for communication with important system
resources, should be labeled with proper SELinux types. If any device files
carry the SELinux type device_t or unlabeled_t, report the
bug so that policy can be corrected. Supply information about what the
device is and what programs use it.
To check for incorrectly labeled device files, run following commands:
$ sudo find /dev -context *:device_t:* \( -type c -o -type b \) -printf "%p %Z\n"
$ sudo find /dev -context *:unlabeled_t:* \( -type c -o -type b \) -printf "%p %Z\n"
It should produce no output in a well-configured system. |
| Rationale | If a device file carries the SELinux type device_t or
unlabeled_t, then SELinux cannot properly restrict access to the
device file. |
| Warnings | warning
Automatic remediation of this control is not available. The remediation
can be achieved by amending SELinux policy. |

| Description | Daemons for which the SELinux policy does not contain rules will inherit the
context of the parent process. Because daemons are launched during
startup and descend from the init process, they inherit the unconfined_service_t context.
To check for unconfined daemons, run the following command:
$ sudo ps -eZ | grep "unconfined_service_t"
It should produce no output in a well-configured system. |
| Rationale | Daemons which run with the unconfined_service_t context may cause AVC denials,
or allow privileges that the daemon does not require. |
| Warnings | warning
Automatic remediation of this control is not available. Remediation
can be achieved by amending SELinux policy or stopping the unconfined
daemons as outlined above. |

| Description | The SELinux targeted policy is appropriate for
general-purpose desktops and servers, as well as systems in many other roles.
To configure the system to use this policy, add or correct the following line
in /etc/selinux/config:
SELINUXTYPE=targeted
Other policies, such as mls, provide additional security labeling
and greater confinement but are not compatible with many general-purpose
use cases. |
| Rationale | Setting the SELinux policy to targeted or a more specialized policy
ensures the system will confine processes that are likely to be
targeted for exploitation, such as network or system services.
Note: During the development or debugging of SELinux modules, it is common to
temporarily place non-production systems in permissive mode. In such
temporary cases, SELinux policies should be developed, and once work
is completed, the system should be reconfigured to
targeted. |

| Description | The Automatic Bug Reporting Tool ( abrt) collects
and reports crash data when an application crash is detected. Using a variety
of plugins, abrt can email crash reports to system administrators, log crash
reports to files, or forward crash reports to a centralized issue tracking
system such as RHTSupport.
The abrt package can be removed with the following command:
$ sudo dnf erase abrt |
| Rationale | Mishandling crash data could expose sensitive information about
vulnerabilities in software executing on the system, as well as sensitive
information from within a process's address space or registers. |

| Description | The cmdport option in /etc/chrony.conf can be set to
0 to stop chrony daemon from listening on the UDP port 323
for management connections made by chronyc. |
| Rationale | Not exposing the management interface of the chrony daemon on
the network diminishes the attack space. |

| Description | SSH's cryptographic host-based authentication is
more secure than .rhosts authentication. However, it is
not recommended that hosts unilaterally trust one another, even
within an organization.
The default SSH configuration disables host-based authentication. The appropriate
configuration is used if no value is set for HostbasedAuthentication.
To explicitly disable host-based authentication, add or correct the
following line in
/etc/ssh/sshd_config.d/00-complianceascode-hardening.conf:
HostbasedAuthentication no |
| Rationale | SSH trust relationships mean a compromise on one host
can allow an attacker to move trivially to other hosts. |

| Description | Disallow SSH login with empty passwords.
The default SSH configuration disables logins with empty passwords. The appropriate
configuration is used if no value is set for PermitEmptyPasswords.
To explicitly disallow SSH login from accounts with empty passwords,
add or correct the following line in
/etc/ssh/sshd_config.d/00-complianceascode-hardening.conf:
PermitEmptyPasswords no
Any accounts with empty passwords should be disabled immediately, and PAM configuration
should prevent users from being able to assign themselves empty passwords. |
| Rationale | Configuring this setting for the SSH daemon provides additional assurance
that remote login via SSH will require a password, even in the event of
misconfiguration elsewhere. |

| Description | Unless needed, SSH should not permit extraneous or unnecessary
authentication mechanisms like GSSAPI.
The default SSH configuration disallows authentications based on GSSAPI. The appropriate

| Rationale | GSSAPI authentication is used to provide additional authentication mechanisms to
applications. Allowing GSSAPI authentication through SSH exposes the system's
GSSAPI to remote hosts, increasing the attack surface of the system. |

| Description | Unless needed, SSH should not permit extraneous or unnecessary
authentication mechanisms like Kerberos.
The default SSH configuration disallows authentication validation through Kerberos.
The appropriate configuration is used if no value is set for KerberosAuthentication.
To explicitly disable Kerberos authentication, add or correct the following line in

KerberosAuthentication no |
| Rationale | Kerberos authentication for SSH is often implemented using GSSAPI. If Kerberos
is enabled through SSH, the SSH daemon provides a means of access to the
system's Kerberos implementation. Vulnerabilities in the system's Kerberos
implementations may be subject to exploitation. |

| Rationale | Even though the communications channel may be encrypted, an additional layer of
security is gained by extending the policy of not logging directly on as root.
In addition, logging in with a user-specific account provides individual
accountability of actions performed on the system and also helps to minimize
direct attack attempts on root's password. |

| Description | To enable the warning banner and ensure it is consistent
across the system, add or correct the following line in
/etc/ssh/sshd_config.d/00-complianceascode-hardening.conf:
Banner /etc/issue
Another section contains information on how to create an
appropriate system-wide warning banner. |
| Rationale | The warning message reinforces policy awareness during the logon process and
facilitates possible legal action against attackers. Alternatively, systems
whose ownership should not be obvious should ensure usage of a banner that does
not provide easy attribution. |

| Description | The RekeyLimit parameter specifies how often
the session key of the is renegotiated, both in terms of
amount of data that may be transmitted and the time
elapsed.
To decrease the default limits, add or correct the following line in
/etc/ssh/sshd_config.d/00-complianceascode-hardening.conf:
RekeyLimit 512M 1h |
| Rationale | By decreasing the limit based on the amount of data and enabling
time-based limit, effects of potential attacks against
encryption keys are limited. |
